Will Weme USB-HDMI adapter work well with Passport?

I'm looking at a Weme Micro-USB SlimPort Adapter on Amazon for about US $15.

Does anyone know if this adapter works as well as the official BlackBerry adapter in terms of streaming via HDMI to a TV, and also being able to charge the Passport at the same time via the side micro-USB port? It looks as though it should work, and is said to carry 1080p, but the specs say only that it will charge a Nexus. I can't tell if this means it will only charge a Nexus.

If this adapter is as good as the BlackBerry adapter, is there a reason to spend $30 vs $15 (Amazon prices for each)?
